Easily assembled optical signal transmission device

Abstract

An optical signal transmitting device includes a substrate, light emitting modules, an optical coupling element, an optical fiber module, and a pressing pole. The substrate has a first loading surface and a second loading surface. The optical coupling element is positioned on the first loading surface and includes a first cladding portion and coupling lenses. Each coupling lens has a first sloped surface and a second sloped surface. The light emitting modules are positioned on the second loading surface and spatially correspond to the respective first sloped surfaces. The optical fiber module is positioned on the first loading surface and includes a second cladding portion and fiber cores. Each fiber core has a bare end. The pressing pole presses each bare end to the corresponding second sloped surface. The refractive indexes of the substrate, the coupling lenses, the fiber cores and the air are n1, n2, n3, n0, wherein n3>n2>>n1>n0.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to an optical signal transmission device.[0003]2. Description of Related Art[0004]Optical signal transmission devices include a number of converging lenses and a number of optical fibers corresponding to the converging lenses respectively. Each of the optical fibers has an incident surface. The converging lenses need to be aligned with the corresponding incident surfaces, and thus light rays converged by the converging lenses can directly enter the corresponding optical fiber. Limited to a relatively small area of each incident surface, it is not easy to align the converging lenses with the corresponding incident surfaces, resulting in relatively low assembly efficiency of the optical signal transmission devices.[0005]Therefore, it is desirable to provide an optical signal transmission device that can overcome the above-mentioned limitations.BRIEF DESCRIPTION OF THE DRAWINGS[0006]Many aspects of the embodiments s...
